A lot of complaintes have been going around lately about things going on with blogs.
First before you compaine, delete any blogs that have javascript that might being screwing up ur profile!
That was my problem, i had one fail script blog and it made my comments, blogs, and more unviewable for myself and others! Make sure that you know what you're doing when u edit ur profile!

Another possibility is a bug in the sites script that is resetting all blogs and bringing back deleted data!! Though this stuff is raising your awesome ranking =D
Hull will fix the bug and if it doesnt work after that then it was done by your own actions and you need to fix it.
bugs are bugs. you don't give them food they wont come. but u feed them trash(screw up script) they take over.
please keep it clean.
